chambe'rnlt fi Such fogging occurs when certain types i'offilm ere :used-,; as is well known in the art. *Thisi'idover'positionoffdislg'32-,is shown in dottd-llines of Fig.1.. .After an exposure is made,

theexposed filmLarea-is wound upon a takeup roll;,znot:zshown.,- During this winding-operation, it is necessary to view the exposure numbers; on

the-film backing strip so as to insure proper positioning or, the filmstrip for the next exposure.

In ordeflto p'ermit such exposure numbering to be viewed fthr i h the viewing. openin l1 and to an noperative" positionfsuchas indicated in broken line, Fig. 1', so as to uncover the red window opening: The disk 32 may be thus slid into and out of window covering position. It is apor othersuitable article which may beinserted parent that the color glass l8 may be mounted ter has secured thereto, substantially at'the cen ter thereof, a stud 33 which extends upwardly through an elongated slot ora er il 'e'fl formed c in the back H adjacent theviewing o e-1111123111, as clearly shown in Figs. 1 and' 2. The outer .enclof the stud 33 is formed with'ari en larged'portion or knob which may b gm m Slide the stud 33 longitudinally of the slot 34 to move the disk 32 into and out of window coveringpo in the slot to turn the knob 35 and hence the disk 32. The stud 33 maybe "made to-form .a tight fit in the slot 34 so as to afford sufficient friction therewith to retain the'disk 32 in its adjusted film indicating position. It is preferred, however, to provide means for positivelyflretaining the disk 32 in its adjusted position.

To this 'endffthe periphery 39 of the disk 32 1 .is formed with aseriesof notches-40 which are arranged to selectively receive a correspondingly a shaped portionfibformed on the'endof one arm, f

This spring and notch arrangesition,. as indicated by dotted and broken lines in Fig. 1.

- As iswell known,'various:'types"of film reqrnre different exposure conditions to insure best re:- sults. Very often; however; relatively Iongintervals of timer'nay elapse between the making of the successive exposmegand during this; timethe operator may forget the precise type of'film with which'the camera is:lfoaded;:. Qbviously under I such conditions, the desired results cannot be obtained. In order: to overcorizlethis" undesirable feature, the presentwinvention provides a; film. indicating device whichicl'earlmshows the; type of film in the camera. 'deticevis adjusted when thefilm is placect the camera, :and zre gardless of the Iapseoftirne; the"; operator can definitely determine uponjinspection ofsthe lievice" the particular. illn'i with which the, camera is loaded,'thus efi'ectively elimmating anigue'sse work onthe partj-of'the operator; -Tor seoure this highly desirable result, the 'di'skifhas one iaee 35 thereof printed, etched, engraved; or otherwise formedwith a series!ofiindicationsflsli'to designate various: types.
